Mount Polley Mine

  • open pit copper/gold mine
  • mill processes ~16,800 tonnes per day
  • commenced operations 1997
  • current mine life to 2026
  • concentrate trucked to Port of Vancouver
  • effective May 2019 Mount Polley operations ceased, and mine was placed on care & maintenance status

Mount Polley operations were suspended in May 2019, and the mine is on care & maintenance status. A resumption of operations is anticipated once the economics of mining at Mount Polley improve.

Extensive remediation work in the areas affected by the 2014 breach has been achieved during the past six years. The mine’s closure will not impact the ongoing environmental monitoring and remediation programs.

Mount Polley has an option to earn a 100% interest in seven mineral claims (3,331 ha), adjacent to the mine. Three target settings occur within the optioned claims and adjacent Mount Polley claims, including a potential northern projection of the high-grade Quarry zone beneath a post-mineral conglomerate unit, a partially tested glacial till covered area where regional magnetics suggests a faulted offset of the Mount Polley Intrusive complex, which hosts the Mount Polley orebodies, is present and a till covered prospective area immediately east of the Southeast zone.

In late 2019, a comprehensive exploration program targeted an area known as the Frypan/Morehead, a largely till covered magnetic “high” which has a similar magnetic response to that obtained over the Mount Polley mine host rock of monzonite and hydrothermally altered monzonite breccia pipes. The area is located west and north of the mine and is approximately 3 by 3 kilometres in size. A total of 948 soil samples were collected and analyzed using the Mobile Metal Ion technique. SJ Geophysics also completed an 80.7 line kilometre Volterra-3D Induced Polarization (IP) survey covering the same grid area. Numerous, high priority targets were outlined and will be tested once final analysis is completed.

During June 2020, the same kind of IP survey was conducted over the Mount Polley mine site to identify the geophysical response of the known mineralization to aid in prioritizing targets on the Frypan/Morehead area. The survey consisted of 81.5 line kilometres and was successful in delineating the known mineralization, as well as outlining several “new” un-tested areas in the vicinity of the mine.

A drill program is being developed to test the geophysical anomalies this year.

Mount Polley is an open pit copper/gold mine with an underground component located in south-central British Columbia, 56 kilometres northeast of Williams Lake. The property encompasses 20,113 hectares, comprised of seven mining leases totalling 2,007 hectares, and 46 mineral claims encompassing 18,106 hectares. Mount Polley mine is owned and operated by Mount Polley Mining Corporation (MPMC), a subsidiary of Imperial.
